In the middle of the Asian Continent lies a "sea of
great mountains", which is unique on Earth. It is the
Tibetan Plateau, known as the "roof of the world",
where there are numerous summits and lakes at an average altitude
of more than 4,000 meters. The Tibet Autonomous Region is located
in the Southeast Tibetan Plauteau.

In the West Plateau is the northeast section of the well-known
Hengduan Shan Range, generally called the East Tibetan Area of
High Mountains and Canyons, with its steep mountain tops and most
of the northern peaks at an altitude of about 5,200 meters. as on
goes down to the south from the north, he will notice that the
height difference between the mountain tops and the canyon
bottoms increase, reaching over 2,500 meters at the extreme
point. Snows at the top never melt all the year round, the
forests on the mountain side dense and luxuriant, the piedimount
field green all the seasons--a beautiful view of the south region
of steep canyons.

Situated amid the Kunlun Shan Range, the Tanggula Shan,
Gangdisi Shan and the Nyanqingtangula Shan, north Tibetis called
"Qiangtang" in Tibetan language which means
"the highland in the north", its usual name
being the North Tibetan Plateau with an altitude of 4,500 meters.
Many basin areas are dotted among the perfectly round mountain
groups sloping midly with a height different of only 300-500
meters.
